C = Current meter systems (current speed, direction, water temperature) are partially functional with some loss of data.
M = Meteorological systems (wind speed,direction, air temperature, air pressure, humidity) are partially functional with some loss of data.
T = Primary telemetry system (satellite or cellular) is not functioning, data is returned via backup telmetry (Argos).

C = Current meter systems (current speed, direction, water temperature) not functioning, no good data returned.
M = Meteorological systems (wind speed,direction, air temperature, air pressure, humidity) not functioning, no good data returned.
T = Primary and backup telemetry systems (satellite or cellular) both not functioning, no data is returned in real time.
